OAR 340-222-0080
Plant Site Emission Limit Compliance
(1)
The permittee must monitor regulated pollutant emissions or other parameters that are sufficient to produce the records necessary for demonstrating compliance with the PSEL.(2)
The frequency of the monitoring and associated averaging periods must be as short as possible and consistent with that used in the compliance method.(3)
Intentionally left blank —Ed.(a)
For annual PSELs, the permittee must monitor appropriate parameters and maintain all records necessary for demonstrating compliance with the annual PSEL at least monthly and be able to determine emissions on a rolling 12 consecutive month basis.(b)
For short term PSELs, the permittee must monitor appropriate parameters and maintain all records necessary for demonstrating compliance with any short term PSEL at least as frequently as the short term PSEL averaging period.(4)
The applicant must specify in the permit application the method that will be used to determine compliance with the PSEL. DEQ will review the method and approve or modify, as necessary, to assure compliance with the PSEL. DEQ will include PSEL compliance monitoring methods in all permits that contain PSELs. Depending on source operations, one or more of the following methods may be acceptable:(a)
Continuous emissions monitors;(b)
Material balance calculations;(c)
Emissions calculations using approved emission factors and process information;(d)
Alternative production or process limits; and(e)
Other methods approved by DEQ.(5)
When annual reports are required, the permittee must include the emissions total for each consecutive 12 month period during the calendar year, unless otherwise specified by a permit condition.(6)
Regardless of the PSEL compliance requirements specified in a permit, actual emissions may be calculated in accordance with OAR 340-222-0051 (Actual Emissions)(4).
